Frequently asked questions
- What are the UK rules for child car seats?
- Children must use a suitable seat until they are 135cm tall or 12 years old, whichever comes first. The seat must be correctly fitted and approved.
- What is an i-Size car seat?
- i-Size is a standard based on a child's height rather than weight. It encourages longer rearward-facing travel and is designed to improve side-impact protection.
- Is Isofix safer than a seatbelt fitting?
- Isofix reduces the chance of incorrect installation by clipping directly to anchor points. A correctly fitted belted seat can also be safe, but is easier to fit wrongly.
